ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 763,595, dated June 28, 1904.

Application filed November 24:, 1903. Serial No. 182,466. (No model.)

ing drawings, and the numerals of reference marked thereon, which form a part of this specification.

My invention relates to improvements in acetylenegas generators; and it consists in the strong, durable, effective, and inexpensive construction hereinafter setforth.

It relates to that class known. as auto matic generators; and my objects are, first,

to furnish a machine which will generate gas while the same is being consumed and cease said generation when no more 1s required and to produce a carbid-holder having superior and perfect operating facilities and one easily built to accommodate any given amountv of carbid, also one easy to care for, to fill and clean, and one safe from explosion. These objects I. accomplish by the use of the compound parts arranged and formed together, as hereinafter described, and particularly pointed out in the annexed claims.

In order that my invention may be clearly understood and readily carried into eflect, I'

will now proceed, aided by the accompanying drawings, fully to describe the same.

Referring to the drawings, Figure 1 is a side elevation of my improved gas-generator shown in section. v Fig. 2 is a detached view of a cup provided with suitable water-tubes. Fig. 3 is a plan view of a grate.

1 is a vessel of suitable size and shape. 2 is a false bottom rigidlyattachedhorizontal therein to the sides and ends thereof.

3 is a lower chamber in the vessel 1, formed by the false bottom '2, and is rendered airtightexcept at a suitable point, hereinafter described, in the false bottom 2.

4 is a pipe of suitable size rigidly fastened at a suitable point in the false bottom 2 and the vessel 28, hereinafter described.

adapted to extend downwardly to near the bottom of the said vessel 1.

5 representsone or more openings in the false bottom. 2 at a suitable point, preferably the center thereof, over which is rigidly attached a drier, constructed, preferably, as follows: A cylindrical chamber 6 of suitable size has its lower end rigidly attached with the The bottom 12 of the receptacle Sis in the form of a funnel, with an opening 13 in the apex thereof. Over the opening 13 I place a shield 14, similar in form to the bottom 12, raised slightly above the said bottom 12, so as to allow a free circulation of air or gas. The receptacle 8 is adapted to contain a purifying agent 1 1, preferably calcium carbid and quicklime or either separately. Over the pipe 4 I arrange a hood 16, as shown in Fig.

3, having a suitable pipe'15, which is adapted to conduct any gas overflowing from the gaschamber 3 t0 the outside of the building, thereby preventing any liability of an accumulation of gas, and consequently an explosion.

17 is a carbid-chamber of a suitable material, provided with flanges 17 at a suitable point thereon and for the purpose as will be hereinafter shown. 18 is a bench suitably fastened on the top of said carbid-chamber 17 and centrally orificed to receive a suitable thumb-screw 19 for the purpose as will be shown. 20 is a cap on the top of said carbidchamber 17, running under the bench l8 and regulated by the thumb-screw 19.

21 is a pipe connecting the chamber 3 with 22 is a shut-off valve in said pipe 21, situated between the chamber 3 and the vessel 28.

23 is a dam in the side walls of the vessel 1, situated in the chamber 3 at the opening of the pipe 21 therein and suitably arranged for the purpose of raising the water above the'end of the pipe 21.

24 is a cup fastened in the side wall of the vessel 28 at the point where the pipe 21 enters said vessel and into which said pipe 21 discharges. 25, 25, and 25 are water-tubes fastened in said cup, with each one a little higher than the other, for the purpose as will be shown. 26 represents apertures at the lower ends of said tubes for the purposes as will be shown.

27 is a spiral wire coil suitably fastened at the lower ends of the side walls of the carbidchamber 17 V and extending one-half around the carbid-chamber.

28 is a vessel provided with a flange 28 on its upper end, the lower end of the carbidchamber 17 projecting downwardly in the said chamber 28 and securely fastened thereto by means of the flanges 17 a and 28 and suitable bolts.

29 is a pipe extending downwardly along the side of the vessel 28 and entering said vessel at a suitable point and then extending upward along the inside of the vessel, said pipe 29 suitably constructed so that when gas is being generated the pressure will keep the pipe 29 evenly filled with water.

29 is a cap projecting over the top of the portion of the pipe 29 which isinside the vessel and is adapted to prevent particles of carbid from falling into and choking said pipe 29.

30 is a grate located a short distance below the carbid-chamber in the vessel 28 and constructed as follows: of light wires 3O and .broad strap-irons 30, running parallel and alternately to each other, and of heavy wires 30, running transversely to said fine wire.

31 is a grate fastened in the chamber 28 a short distance above the bottom thereon and provided with finer meshes than those of the grate 30. V

32 is a shaker or stirrer in the bottom of the vessel 28, provided with a handle 32 and arms 32. Said shaker is adapted to prevent the hydrate from becoming packed in the bottom of the vessel 28.

33 is a vertical pipe connected to the horizontal pipe 34 by means of a joint 33*, said pipe 34 being connected to another vertical pipe, 35, by means of a joint 35 said pipe 35 being securely fastened in the bottom of the vessel 28 at any suitable point. Said pipe 33 and the joint 33 are adapted to be turned down in a horizontal position, so that the end of said pipe is a little lower than pipe 34. This allows the accumulated particles of hydrate, mixed with water which enters from the pipe 21, to run from the vessel 28.

36 is a pipe connected to the carbid-chamber 17 at any desired point and connecting with the pipe 21 at a point between the shut-off valve 22 and the vessel 1 and is adapted to carry into the said chamber 3 any gas which may be in the said carbid-chamber 17 after generation has ceased.

36 is a shut-off valve at any suitable point on the pipe 36.

The mode of operating my improved acetylene-gas generator is as follows: The carbidchamber 17 isfilled with calcium carbid. The

cap 20 is placed on the top of said carbidchamber and suitably secured air-tight thereto by means of the set-screw 19. The stopcock 22 is then opened. The receptacle 8 is then filled with the purifying agent 14 and placed in the chamber 6, whereupon the cover 10 is placed and secured in position and rendered air-tight. WVater is then introduced into the vessel 1 in sufficient quantity to fill the chamber 3 by reason of the pipe 4, the air contained in said chamber 3 being allowed to escape by means of the house-pipe 11, which is left open for that purpose. A quantity of water is deposited in the vessel 1 after the chamber 3 is filled, so as to give the gas the required pressure. As the water rises in the chamber 3 and flows over the dam 23 the same is conducted into the cup 24 by means of the pipe 21. The water then runs down the tube 25 and jets out through the aperture 26 upon the carbid resting on the wire coil 27, and the generation of gas commences. If less of the gas is being used than is generated by the water jetting from the tube 25, the pressure holds the water in the chamber 3 at such a height that just enough 'runs over the dam 23 to supply the tube 25. If as much is used as is generated by the water jetting from the tube 25, the pressure is less and the water runs over the dam 23 and fills the cup 24 until the water flows down the tube 25 and two jets play on the carbid; similarly for the tube 25 or any number that may be used. When the consumption of gas ceases, the volume of gas generated by the moisture in the generator flows into the chamber 3 and presses the water contained therein out through the pipe 4 into the vessel 1. As the water is forced by the pressure of gas out of the chamber 3 the same ceases to flow over the dam 23 into the pipe 21 and the cup 24, thereby discontinuing the generation of gas until the gas is used out of the chamber 3 sufficiently to allow the water to rise and flow over the dam 23, whereupon generationbeginsagain and continues until stopped, as above stated. Should water by accident find its way into the generator until the generator has filled the chamber 3 completely with gas and forced the water from said chamber 3 through the pipe 4 into the vessel 1 until the lower end of the pipe 4 is exposed, the surplus gas will find its way through the said pipe 4, where it will be caught by the hood 16, whereupon the same will be conducted to the open atmosphere by the pipe 15, thus preventing the accumulation of gas in a room where light introduced would cause an explosion. If any gas should by chance creep up between the chunks of carbid, it will be carried into the gasometer by means of the pipe 36. If by chance more gas should be accumulated in the vessel 28 than could be carried off by the pipe 21, the pressure would force the water out of the pipe 29, and thus the gas would escape and prevent an explosion.

The gas before use passes through the holes 5 into the chamber 6 and from there through the opening 13 in the bottom 12 of the recep tacle 8, where it is purified and cooled by the agent 14, contained in said receptacle 8, whereupon said gas proceeds into the housepipe 11, where it may be used as desired.

When it is desired to fill the carbid-holder, shut the stop-cocks 22 and 36 and loosen the set-screw 19 and remove the top 20.

When it becomes necessary to remove the decomposed carbid from the bottom of the vessel 28, loosen it by means of the shaker 32 32 32". Then turn the outlet-pipe 33 to a position a little lower than the bottom of the vessel 28. The hydrate decomposed by the waste water in the vessel 28 will run through the outlet 33 34 35. The screens 30 and 31 are to hold the carbid until it is sufl iciently decomposed to fall through.

Although I have shown my improved acetylene-gas generator in combination with a particular style of gasometer, still it may be used with any form of gas-holder.

I have shown but three tubes fastened in the cup 24:. In practice, however, any number may be used.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

1. In a gas-generating machine the combination with a gasometer, generating-chamber and carbid-chamber of a suitable gas and wa-' ter conduit connecting said generating-chamber to said gasometer, a cup at the entrance of said conduit into said generating-chamber, spray-tubes arranged in said cup at different elevations, a U-shaped safety escape-pipe located in the side of the said generating-chamber, and means for cleaning said generatingchamber, all as set forth.
